Lockheed Martin delivers MUOS waveform for secure communications

SUNNYVALE, Calif.-Lockheed Martin Corp. has delivered the software waveform for the U.S. Navy's Mobile User Objective System (MUOS). The new waveform will enable military satellite communications terminal providers to deploy equipment that makes use of enhanced capabilities.

The MUOS narrowband tactical satellite communications system will provide secure communications capabilities with features such as simultaneous voice, video, and data for mobile and remote users. Satellites for MUOS are equipped with a wideband code division multiple access (WCDMA) payload, providing a 16-fold increase in transmission throughput over the current ultra-high frequency (UHF) system.

The advances come from a previously commercial waveform that has been tailored for use with the new WCDMA payload. The U.S. Government made the waveform available for military satellite communications terminal providers through the joint tactical networking center (JTNC) information repository. Contractors can integrate the waveform into MUOS-compatible terminals.

Each MUOS satellite also includes a legacy UHF payload compatible with the current UHF follow-on system and legacy terminals. The dual-payload design will assist in the transition as UHF is phased out.

The first MUOS satellite and associated ground system are providing initial on-orbit capability. The second satellite will be launched in July.

Lockheed Martin is under contract to deliver five MUOS satellites and associated ground system to the U.S. Navy. Lockheed Martin Space Systems is the MUOS prime contractor and system integrator for the program, which is handled by the Navy's Program Executive Office for Space Systems and Communications Satellite Program Office.
